edit: did some research and apperently theres some stars bigger than our galaxya galaxy contains billions of solar systems
this is juts crazy..
The Biggest Stars are comparable to the size of a Solar System.

I know, right? Have a perfect plan of salvation that accounts for every last person is really lame. You'd think everyone would be content with billions of people going to hell with only a few "chosen" ones getting a random chance at heaven. But, nooooo, the Mormons had to think of all angles and save everyone.

It might be impossible, if you count black holes as dark stars. As a black hole grows in size, the distance between the singularity and the event horizon grows. As this distance grows, the effect of gravity at the event horizon diminishes. Theoretically you could have a black hole that is so big that matter may not be pulled into it, because the gravity at the event horizon is so low. But this is pure speculation on my part.

No, impossible.
Consider:
The Schwarzchild radius for the Milky Way is about 10^12 kilometers.
If you took all the mass in the Milky Way, turned it into pure hydrogen and packed it into a ball it would have a radius of just 10^11 kilometers.
Since actual stars are much denser than hydrogen we can conclude that a star with the mass of a galaxy will inevitably collapse into a black hole.

Why?
1) There are not enough gas clouds to form such a star at least in the observable Universe.
2) As Star gets more massive it will collapses into a black hole. http://en.wikipedia.org/wiki/Chandrasekhar_limit explains the basics.
The reason why huge stars don’t turn into black hole right away it’s because Stars produce energy through nuclear fusion so the heat produced by these reactions prevents gravitational collapse what could turn into a black hole if mass is large enough.
So the larger a star is the quicker it burns via nuclear fusion so it’s impossible to support its mass at a Galactic level.

Don't bother. I did the math on a galaxy sized star a few posts up and nobody even noticed cry

That's such a load of BS. If someone's life couldn't get them in heaven, why would God care what others who don't stand for them did posthumously? It says nothing about the person.
That's because you are not aware that there is an existance after this life, but before judgement day, where the person can chose to accept or deny the ordinances done on their behalf.
🙂
Why would a person chose to deny the ordinances done on their behalf? It is much harder to accept the plan of salvation as a spirit that willingly did evil, knowing it was wrong.

impossible
a star can be thought of as a huge furnace pouring out just enough energy so that gravity doesn't pull it together. Too much energy, and all of the atoms would just spew out in all directions, too little, and it collapes.
So, the energy at the core of a star comes from fusion. We tend to talk about Hydorgen (1+ 1n particles in the atomic nucleus), but bigger and hotter stars can actually fuse more complex substances. What happens are then layers of fusion, Hydrogen at the outer, then oxygen, etc.
The biggest and hottest stars in the universe are thought to only comprise of 4 or 5 such layers (I only took first year astronomy, 5 years ago, so this is not the word of god), however, there is a theoretical limit. This is because, to move up to fusing higher order elements in their core, stars would require exponential increases in power produced. To move above the current theoretical limit of 4/5 layers would, iirc, require more energy than exists in the universe.
